The Float Process
At the heart of the world's glass industry is the float process - invented by Sir Alastair Pilkington in 1952 - which manufactures clear, tinted and coated glass for buildings, and clear and tinted glass for vehicles. The process, originally able to make only 6mm thick glass, now makes it as thin as 0.4 mm and as thick as 25 mm. Molten glass, at …

Finally, the friction force between the polishing film and the quartz glass surface promoted the plastic flow of the shallow surface flow layer. This plastic flow can quickly cover the grinding damage exposed in the polishing process and the plastic scratch introduced by the polishing, thus ensuring the smoothness of the surface.
